This for my 14 month old. She's been doing this since about 4 months old (knock on wood!) And she still has 2 naps (9am-11am) (2-4pm)
I don't consider myself old, but might be a fuddy duddy regardless
I think lots of sleep is good for LOs and I put quite a bit of effort into getting her routine down when she was young. I do get the occasional comment about how that's too early but not very often. When I do I just ignore it because I'm not the one with black circles under my eyes
